Early Warning System

Modern vehicles are equipped with onboard computers that monitor the critical systems in your car and warn you when something is going wrong. Your check engine light is your vehicle computer’s way of telling you that there may be a problem and your car requires service as soon as possible.

So Many Possibilities

The reasons for a check engine light activation range from something as simple as a loose gas cap to something as serious as a faulty catalytic convertor. Below is a list of a few of the possible problems that could cause your check engine light to activate.

Loose gas cap

Problem with the MAF sensor or circuit

System running too lean or too rich

Cylinder misfire

Knock sensor circuit malfunction

Insufficient EGR (Exhaust Gas Recirculation) flow

Catalyst system efficiency below threshold

Faulty oxygen sensor

These are just a few of the hundreds of causes and symptoms that would result in an engaged check engine light. Decoding your dashboard is a science. Learn more about how to decode it here!

Free Code Retrieval Process

Our Free Check Engine Light Code Retrieval Service provides you with quick and accurate answers from a professional Pep Boys technician. When the check engine light turns on, a fault code or OBD II code, detailing the nature of the issue is registered in your vehicle’s diagnostic system computer. This fault code is stored and can only be retrieved with specialized equipment that can communicate with your vehicle’s diagnostic system computer. We use that equipment to pull the code from your computer, analyze the findings and provide you with a game plan to get your car back on the road. The Check Engine Light Code Retrieval is free and our diagnostic services start as low as $89.99.

Ignorance is not Bliss

Do not panic – but don’t ignore that light - especially if it is flashing.

A solid glowing check engine light could be indicating a problem that is easily fixable. Your vehicle could require a simple adjustment or a replacement part. Driving long distances with this light activated could result in a larger problem down the road. It is safest for you and your passengers to learn what is going on with your vehicle sooner rather than later so that you can take the necessary measures to fix the issue.
